Title:
INTERMITTENT OPERATION RADIO EQUIPMENT
Document Type and Number:
Japanese Patent JP2011055186
Kind Code:
A
Abstract:

To suppress wasteful power consumption of a power supply circuit of a DC voltage conversion method even if an intermittent radio communication is performed involving a sleep state of low current consumption, while being operated on a battery.

A CPU13 stops a DC voltage conversion operation and an operational power supply by controlling a power supply circuit 11 during a sleeping period, but performs a DC voltage conversion operation and an operational power source supply by controlling the power source circuit 11 during a radio communication operation period. A sleep power source circuit 14 supplies a sleep operation power required for a sleeping operation to the CPU13 during a sleeping period.
